A free alternative to Adobe Acrobat for signing
Adobe Acrobat is powerful, but for the simple job of signing a PDF it’s overkill — it costs a monthly subscription, it’s a heavy install, and it pushes you toward an account and cloud storage. If you just need to sign a document and send it back, you don’t need any of that.
PDFArena does the one thing most people open Acrobat for: it lets you add a signature to a PDF and download it. There’s nothing to install and nothing to pay. It runs in the browser you already have, on whatever device you’re using.
Nothing to install, nothing to learn
Open the page, choose your PDF, sign, download. There’s no setup, no licence key, and no learning curve — and because the file is processed locally, it never leaves your device.
How it works
Sign your PDF in three steps.
No learning curve, no account setup — done in under a minute.
Add your signature
Draw it with a mouse or finger, type your name, or upload a signature image. Drag it into position on the page.
Download the signed PDF
Click download and the signed PDF saves to your device, signature embedded permanently — ready to send.
